easy operation industrial coal fired steam boiler coal

Gas-fired easy operation industrial coal fired steam boiler coal and gas steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas steam boiler and gas steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answer the same model as compared to steam boilers or gas steam boiler energy conservation, we can roughly be calculated next-ton per hour boiler full load of work to 150-160Kg coal according to the market value of fuel gas and gas to about 80m3 . A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.

The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

After the gas hot water boiler hot water boiler vaporization emergency 1. Vaporization handler circulating pump stops abnormally pump failure caused by: ① blower stops running immediately. ② immediately open the door, take measures to pressure the fire, lift the chute gate, cutting off the supply of coal grate. ③ In the case of boiler pressure not greater than 0.6MPa (600KPa), the exhaust valve to follow, only a sharp rise in pressure in the boiler deflated, used only relief exceeds 0.9MPa, and the exhaust process to be carried out slowly, prevention boiler due to loss of pressure and more violently again vaporized. ④ close the boiler water, water main gas valve. ⑤ open stop valve recirculation line, to ensure that the water supply pipe velocity convection heating surface (economizer) to prevent re-vaporization of the economizer. ⑥ The operation of the above operation, at the same time to pay the boiler to reduce the boiler water temperature and the furnace pressure. ⑦ After the boiler pressure is normal, i.e., opening the standby circulating pump, into the normal combustion. 2. Treatment failure or sudden loss of power boiler vaporization of power: ① immediately open the door, lift the coal chute slide gate to take pressure fire measures to reduce the oven temperature. ② Grate with the fastest speed in order in the shortest time to fire onto the slag tap. ③ the degree of treatment in the first case. Once a short time can not supply heating network system, antifreeze should take emergency measures. 3. Due to excessive heat boiler boiler vaporization process: ① the immediate closure of the drum, induced draft fan. ② immediately open the door, take measures to pressure the fire, lift the supply of coal chute slide gate, off of coal, while the grate into fast gear. ③ In the case confirmed the presence of water, the boiler can supply water to the boiler body, boiler out of the water while closing the main valve. ④ Open line stop valve recirculation pump to ensure water velocity convection heating surface of the pipe, to prevent the economizer again vaporized. ⑤ Open circulating pump with jog mode, jog each time less than 30 seconds, again less than one minute jog interval. Jog purpose is to reduce the boiler water temperature, while preventing a large amount of steam into the pipeline system. ⑥ back into place after the safety valve, circulating pump running, and then the normal burning stove. 4. Water boiler system run vaporization process due to water loss, loss of pressure caused by: ① immediately closed drum, induced draft fan. ② out of the water while closing the main valve and the boiler circulating pump. ③ take the same measures to cool the furnace tube described above. ④ Open stop valve recirculation line. ⑤ rely exhaust valve until the safety valve back into place. ⑥ until the boiler water temperature drops below 50 ℃, when the temperature of the furnace temperature less number 200 ℃, again within the boiler feed water, water course to be carried out slowly, to prevent harm to the boiler when the temperature is too large. ⑦ After processing leakage fault, the system time to the replenishment, and out of the water boiler always open the valve, and the circulating pump, and then normal combustion.
